LZZBJ9-35(LZZB8-35A)
This series of current transformers features a fully enclosed structure with epoxy resin cast insulation. They are suitable for use in power systems with a rated frequency of 50 Hz or 60 Hz for electricity metering. This type of current transformer eliminates oil contamination and fire hazards, reduces maintenance requirements, and meets the requirements for oil-free operation. This type of current transformer uses epoxy resin as the primary insulation material, offering resistance to arcing, UV radiation, and aging. The core is made of high-quality, high-permeability material that has undergone annealing treatment. Both the primary and secondary windings, as well as the core, are encapsulated in epoxy resin, ensuring excellent insulation performance.
